District data acquisition capability evaluation method based on CRITIC-AHP

Abstract

The invention discloses a transformer area data acquisition capability evaluation method based on CRITIC-AHP, and relates to the field of power grid operation and maintenance. At present, visual transformer area data acquisition capability information is lacked, so that accurate data support is lacked in the aspects of transformer area investment decision, operation and maintenance service and the like. The method comprises the following steps of: acquiring index item data in an index system by using an electricity utilization information acquisition system, and performing preprocessing such as screening, cleaning and normalization; a CRITIC method and an AHP method are adopted to determine objective weights and subjective weights of the indexes respectively; combining the subjective weight with the objective weight to obtain a comprehensive weight; and calculating according to the comprehensive weight and the acquisition capability evaluation function to obtain an evaluation result, thereby realizing comprehensive quantitative evaluation of the transformer area data acquisition capability. According to the technical scheme, the expert experience and the comprehensive weight of the data information can be reflected, the comprehensive quantitative evaluation of the transformer area data acquisition capability is realized, and the evaluation of the transformer area data acquisition capability is accurate and reasonable.

Description

technical field [0001] The invention relates to the field of power grid operation and maintenance, in particular to a CRITIC-AHP-based evaluation method for data acquisition capability of a station area. Background technique [0002] With the comprehensive application of the electricity consumption information collection system of the State Grid Corporation of China, the electricity consumption information collection system aiming at "full coverage" of power user data can collect, process and monitor the electricity consumption information of power users in real time. It has functions such as automatic collection of electricity consumption information, abnormal measurement monitoring, power quality monitoring, electricity consumption analysis and management, and information exchange of intelligent electrical equipment. As the most basic unit of power supply, Taiwan District connects power production and power consumption. The level of management in Taiwan District reflects t...

Problems solved by technology

The traditional state evaluation of the station area mainly constructs the evaluation index system by selecting characteristic indicators from the two aspects of the structure and state of the station area. Although the comprehensive evaluation method is simple and easy to implement, this type of method only reflects the subjective importance of the index, often ignores the characteristics of the data itself, and does not reflect the objective importance of the index. The comprehensive state evaluation of the district lacks certain objective rationality

Moreover, there is still a lack of an evaluation index system and evaluation method for the data collection capability of the station area, and the lack of intuitive information on the data collection capability of the station area, which leads to the lack of accurate data support in the investment decision-making and operation and maintenance services of the station area.
